FAQs
For optimal performance, ensure adequate ventilation around the vented XFMR, maintain clearance as specified by Eaton, and accommodate the 24 in depth, 30.5 in width, and 43 in height footprint. Verify mounting orientation and secure the unit in a dedicated transformer room or panel area designed for 680 lb equipment. Include proper cable entries and strain relief per local codes.
The K-Factor nonlinear design mitigates heating from harmonic currents, improving thermal stability and insulation life. This results in steadier output under non-sinusoidal loads common in industrial facilities. In practice, you’ll see more consistent voltage regulation, reduced cooling load, and longer maintenance intervals in high-harmonic environments.
Yes. The N48M28T4521CULS43 is specified for three-phase operation with a 480-208Y/120 V configuration, aligning with standard industrial control panels and motor control centers. Its 45 kVA rating supports mid-size loads while maintaining system voltage stability and ease of integration with Eaton or compatible auxiliary components.
The unit carries UL Listed certification, indicating compliance with recognized safety standards for electrical equipment. This certification simplifies supplier qualification, supports regulatory audits, and reduces risk in procurement. While other certifications are not listed here, UL compliance is a critical factor for mission-critical and safety-conscious environments.
ROI improves through reduced maintenance due to better thermal management, fewer transformer assemblies needed thanks to its 45 kVA rating, and lower energy losses from efficient design. The vented, K-Factor approach helps sustain uptime in demanding production lines, while UL certification shortens procurement cycles and supports compliance-driven cost savings over the asset lifecycle.
